1. The problem statement, all variables and given/known data A 0.5kg puck on a frozen pond is given an initial speed of 20m/s. If the puck always remains on the ice and slides 115m before coming to rest, determine the coefficient of kinetic friction between the puck and ice. 2. Relevant equations mass= 0.5kg force of gravity= mass x gravity = (0.5)(9.8)= 4.9N displacement= 115m V1= 20m/s V2= 0m/s uk= ? 3. The attempt at a solution I have no idea where to start.
